Hey Elliot!
Have you tried adding a new “ceiling fan” device, going to advanced, clearing the check box for Database matching, and then manually recording each remote key press to a button named something reasonably close to the actual AC remote button?
I’ve used “ceiling fan” and “fireplace” device types with raw recording all of the original remote’s buttons to successfully branch out from officially supported devices. (If you use “generic device” you get a lot fewer buttons in BOND to choose from)
See here for an example:
